摘要
海上油气田开发初期井资料相对较少,利用有限的几口探井、评价井想认清楚油气田的构造、储层特征无疑相当困难,如何在地质认识不确定性较大的情况下实现油气田的高效开发是海洋石油工作者一直努力解决的难题。陆丰X油田位于陆丰X构造西高点,在油田翼部构造不落实、动油水界面不确定的情况下,为高效开发该油田,经研究决定全部采用水平井开发,钻投时间间隔明显缩短。在水平井钻探过程中,充分利用随钻测井技术,不仅为水平井钻探地质导向提供依据,保证了对水平井轨迹的有效控制及完井方式的合理制定,也深化了该区的地质认识,促进了整个方案高质量、高效率的完成。
In the early development of offshore oil-gas fields,there were less data of oil wells,for the evaluating wells,it was difficult to study the structural features and reservoir characteristics clearly.Petroleum Geologists have been grappling with the problem for a long time that how to raise the development effectively when the geological cognition was uncertain.Lufeng X Oilfield was located in the west high part of LFX structure.On the conditions of uncertain wing structure of the oil field and the dynamic oil-water interface,and for a high efficient development of the oilfield,it was decided that horizontal wells should be deployed for oilfield development and drilling intervals were obviously shortened.During the horizontal well drilling,LWD technology not only plays an important role in geological guidance,the effective control of well trajectory and reasonable well completion method are ensured,also the geological understanding to the oilfield is deepened,the completion of the whole high quality and high efficiency scheme is promoted.
